MAGEMin, a new and efficient Gibbs free energy minimizer: application to igneous systems

Abstract

<p>Modelling stable mineral assemblage is crucial to calculate mineral stability relations in the Earth&#8217;s lithosphere e.g., to estimate thermobarometric conditions of exposed rocks and to quantify the fraction and composition of magma during partial melting. Accurate prediction models of stable phase are also fundamental to model trace element partitioning and to extract essential physical properties such as, fluid/melt/rock densities, heat capacity and seismic velocities. This thus forms a crucial step in linking geophysical observations with petrological constraints.</p><p>Here, we present a new Mineral Assemblage Gibbs free Energy Minimizer (MAGEMin). The packa..
